Compressor description by Ralkin

Refers to RefComp 134-S series semi-hermetic screw compressors designed for R134a applications, encompassing models 110, 120, and 140. This series is characterized by compact design, low noise, and high efficiency, meeting the requirements for advanced refrigeration and heat pump systems.

Model Identification

• 134-S: Refers to the RefComp 134-S Series of semi-hermetic screw compressors.
• Suffixes (-110, -120, -140): Indicate the specific model displacement within the series, denoted by codes (071, 081, 091, 101, 110, 120, 140, etc.).

Technical Features:

• Rotor Design: Optimized rotor design specifically based on the characteristics of R134a.
• Integrated Design: High integration of components such as filters, shut-off valves, and temperature sensors for compact structure and higher reliability.
• Safety & Monitoring: Equipped with a motor protection module, dynamic monitoring, and operation information tracking for predictable reminders and safety protection.
• Durability: Pairs of bearing combinations ensure long service life, high load capacity, and low noise.
• Oil Separation: Oil separator and compressor are integrated for high oil separation efficiency and compact structure.
• Maintenance: Built-in precision suction filter that is easy to replace and maintain.
• Installation: Suction/Discharge shut-off valves are rotatable for simple and flexible installation.
• Control: Adjustable cooling capacity allowing step or stepless control.

Model 134-S-140

• Displacement (50/60 Hz): Data not explicitly provided in the specific table row for 140 in the first segment (Table cuts off at 140 but data line ends before 140 data in first table, however looking at second table 160 starts. Let's re-read the data carefully).

Correction on 134-S-140 data extraction based on provided text blocks: The provided data table structure is split: Block 1: Models 071 through 140. Data lines: Displacement, Weight, Oil Charge, Capacity Control, Standard Motor. Block 1 Data Row 1 (Models 071-140): Displacement values provided for 071, 081, 091, 101, 110, 120. The column for 140 exists in the header but the data row for displacement seems to end or align such that 140 data is missing in the first block? Let's look closer.

Text: Model 134-S 071 081 091 101 110 120 140 Text: Displacement ... 270/324 307/368 344/413 380/456 413/496 480/576 There is a gap in the data provided for Model 140 in the Displacement, Weight, and Oil Charge rows in the first table block. The second table block starts at Model 160.

Wait, looking at the raw text again: Model 134-S 071 081 091 101 110 120 140. Then the next line has 6 data entries. It is highly likely the 140 data is missing or the header extends beyond the data provided in that specific chunk, OR the 140 is skipped in the data listing.

However, usually, these prompts imply the data is there. Let's look at the second block. Model 134-S 160 180 210 220 240 270 300.

It appears the specific displacement, weight, and oil charge for Model 140 is not explicitly present in the provided text snippet between 120 and 160. The header lists 140, but the data rows (Displacement, Weight, Oil) only list values for 071 through 120.

Self-Correction/Refinement: I must stick only to the provided data. I will list the specs for 110 and 120 fully. For 140, I will note the shared characteristics (Capacity Control, Motor) but indicate that specific displacement/weight/oil data was not explicitly detailed in the provided text segment compared to the adjacent models.

Actually, let's re-read the first table line carefully. Model 134-S 071 081 091 101 110 120 140 Displacement ... 270/324 307/368 344/413 380/456 413/496 480/576 There are 7 model headers and 6 data values. It is ambiguous where 140 falls or if it's omitted. Given the instruction "Use Only the Provided Data", I will provide the specs for 110 and 120 which are clear, and for 140, I will list the available common specs but omit the specific displacement/weight/oil if not clearly associated.

Alternative Interpretation: Sometimes OCR or text extraction drops a column. But I cannot invent it. I will present 110 and 120 clearly. For 140, I will state the common features.

Wait, looking at the spacing: 071, 081, 091, 101, 110, 120, 140. Data: 270, 307, 344, 380, 413, 480. It is highly probable the 140 data is missing from the source text provided. I will explicitly list the data for 110 and 120, and for 140, I will list the Capacity Control and Motor info which is shared, and omit the specific numeric specs to avoid hallucination.
